Testimonials
From beginning to end I thoroughly enjoyed the whole experience. The amount of knowledge I have gained over the three days is phenomenal and given me a greater understanding of my current studies - the C.A.T. course.
I will definitely use all my notes and knowledge gained over the past few days to succeed in the course and any further education. Both David & Barry were great tutor's for our class and I hope to stay in contact with them as I pursue my career path of hopefully one day becoming an IRV.
The 1-to-1 tutor time gave me the opportunity to gain some career guidance on which paths to follow on completion of my C.A.T. course, which I can't wait to get started on. It was lovely to get a 'hands on' experience with the different tools of the trade and the gemstones and jewellery.
